Alcoholic hepatitis is an acute and severe liver disease associated with high mortality rate. This study was conducted to develop the instrument of criterion for symptoms improvement after temperance. We made the symptoms improvement questionnaire for alcoholic hepatitis patients through reviewing traditional oriental medical literatures and got advices from the advisor committee with delphi technique. The advisor committee on this study was organized by 10 professors of internal medicine of oriental medical colleges nationwide. The questionnaire was composed of questions about 10 symptoms - fatigue, pain, anorexia, abdominal bloat, heaviness of the body, itch, nausea, sleep, dryness in the mouth and stools. We named it Alcoholic Hepatitis Symptoms Improvement Questionnaire(AHSIQ). We surveyed 65 male alcoholic hepatitis patients and checked liver function profile and AHSIQ before and after temperance four times for six weeks. As a result of factor analysis the scales of AHSIQ had content validity and construct validity. And internal consistency reliability was good(Cronbach's alpha=0.768-0.871). The total scale scores were statistically significant in gamma-GTP related validity. We suggest that AHSIQ would be effective for measuring symptoms improvement degree in alcoholic hepatitis patients through further investigations with larger clinical trials.

This experiment was carried out to establish a proper method of indocyanine green(ICG) excrection test for a applicable liver function test in three Korean native cattle average weighing about 450kg and dairy cattle parity of 3~5. The results obtained the half life($T^1/_2$), fractional clearance rate(KICG), retention rate and plasma enzyme activities before or after injection of ICG were as follows. 1. The maximum absorbance of ICG in plasma was at 805nm. 2. Average half life and fractional clearance rate following the injection of ICG 0.25mg/kg body weight were $5.53{\pm}1.27$ minute and $0.131{\pm}0.031$/minute in Korean native cattle, $4.55{\pm}0.68$ minute and $0.156{\pm}0.031$/minute in dairy cattle, respectively. The ICG removal rate was exponentially liner for the first 15 minutes after injection both of Korean native cattle and dairy cattle. 3. Average plasma retention rate when 10, 15, 30 minutes after injection was $35.7{\pm}13.9$, $23.2{\pm}7.1$, $10.8{\pm}3.5%$ in Korean native cattle, $26.8{\pm}3.3$, $14.2{\pm}1.2$, $5.5{\pm}2.2%$ in dairy cattle, respectively. 4. Plasma enzyme activities(AST, ALT, r-GTP) were no variation among the before, during and after injection of ICG. From these results, ICG excretion test to cattle is applicable to evaluation of liver funtion in both clinical and research, and adopted the 15 minutes plasma sample as the sample taken at the ideal time for comparative purposes.

The purpose of this study is to examine the nutrition knowledge, characteristics related to, nutrient intakes, anthropometrics, biochemical indices of university female students by major (food and nutrition versus physical science). Data were taken from 120 university female students (60 from each major) and the results follows. The mean age of the subjects was 19.6 years old. Most of subjects responded that they were healthy; subjects majoring in physical science scored higher in regular exercise (p < 0.01) and were more satisfied with their own body figures (p < 0.01), compared with the counterparts. The total nutrition knowledge score was $81.01{\pm}12.3$ for food and nutrition majors and $72.5{\pm}15.2$ points for physical science majors. (p < 0.01) The percentages of body fat were significantly higher in the food and nutrition students than the counterparts. (p < 0.001) The result of biochemical analysis showed that both groups were in normal range. But there was some statistically significant difference between groups in GTP, HDL-cholesterol and ALP levels. It suggests that regular exercise might have a positive effect on the body. This study showed that although both groups had different knowledge of nutrition, there was not much difference in the intakes of nutrients. But especially, the intakes of calcium and iron were quite low in both groups. Subjects majoring in Physical science had more lipid intake, but they had lower body fat. This suggests that regular exercise in this group might have effects on the percentages of body fat. In future study, nutrition education might be planned to increase nutrition knowledge and to connect nutrition knowledge to eating behaviors and to promote health to regular exercise. Also, the desire and the social perception for pursuing alean body figure and being underweight should be changed for optimal health.

The 5 year follow up study was conducted to assess the positive seroprevalence of HbsAg and magnitude of new cases in a steel manufacturing big scale workpalce. About 2,000 serum samples collected from 1998 to 2002 for hepatititis B surface antigen(HBsAg), antibody to HBsAg(anti-HBs), sAST, sALT, r-GTP, total cholesterol, and triglyceride were tested. The commercially available enzyme-linked immunosorbent assay was utilized in serologic test of hepatititis B surface antigen (HBsAg), and antibody to HBsAg(anti-HBs). The preceived seroprevalence rates in the study were ranged 6.3~6.9%. The seroprevalences of HbsAg were 4.3~4.9% among the age of thirties, a significantly decreased seroprevalence compared with those among other age groups(in forties, 7.1~8.2%, and in fifties 7.1~7.6%). The positive seroprevalence of anti-HBs were 71.0~77.9%. A new case was not detected in the group.

In this experiment, three different diets were produced to investigate the effects of Jeju native chicken meat, from chickens that were fed a tangerine by-product, on physiological activities in rats. The first diet did not contain any chicken (TS), the second diet contained 10% chicken that had not been fed the tangerine by-product (T0), and the third diet contained 10% that had been fed the by-products (T1). These diets were provided to 11-week-old male rats for four weeks. Weight gain, feed intake, feed efficiency, liver, kidney, and epididymis fat weights were not significantly different among the TS, T0, and T1 groups. Total lipid, triglycerides, and cholesterol levels in the liver were significantly lower in T0 and T1 than in TS (p<0.05). And total lipid, phospholipid, triglycerides, total cholesterol, HDL-cholesterol, DL+VLDL-cholesterol, HDL-cholesterol/total cholesterol, and atherogenic index levels in the blood serum were similar between T0 and T1, which did not present any significant differences. The feed containing the tangerine by-product did not cause any statistically significant differences in serum protein, glucose, or hemoglobin. Finally, T0 and T1 showed similar trends in terms of $\gamma$-GTP, ALT, AST, and ALP activities, which again did not present any statistically significant differences.

The role of residue C323 in catalysis by human glutamate dehydrogenase isozymes (hGDH1 and hGDH2) was examined by substituting Arg, Gly, Leu, Met, or Tyr at C323 by cassette mutagenesis using synthetic human GDH isozyme genes. As a result, the $K_m$ of the enzyme for NADH and ${\alpha}-ketoglutarate$ increased up to 1.6-fold and 1.1-fold, respectively. It seems likely that C323 is not responsible for substrate-binding or coenzyme-binding. The efficiency ($k_{cat}/K_m$) of the mutant enzymes was only 11-14% of that of the wild-type isozymes, mainly due to a decrease in $k_{cat}$ values. There was a linear relationship between incorporation of [$^{14}C$]p-chloromercuribenzoic acid and loss of enzyme activity that extrapolated to a stoichiometry of one mol of [$^{14}C$] incorporated per mol of monomer for wild type hGDHs. No incorporation of [$^{14}C$]p-chloromercuribenzoic acid was observed with the C323 mutants. ADP and GTP had no effect on the binding of p-chloromercuribenzoic acid, suggesting that C323 is not directly involved in allosteric regulation. There were no differences between the two hGDH isozymes in sensitivities to mutagenesis at C323. Our results suggest that C323 plays an important role in catalysis by human GDH isozymes.

Holotrichia was tested for the effects on damages of liver tissue induced by bromobenzene. Holotrichia was treated firstly into samples, and then bromobenzene intoxicated animal models were set with them. In vitro, the level of lipid peroxide in tissue of liver proportinally decreased with the level of concentration of extract prepared from Holotrichia It was much more decreased, when lipid peroxidation was induced with ferrous iron ($Fe&{+2}$). In vivo, after the extract was administered to the animal model for twenty days, the level of lipid peroxide in liver decreased compared to that of bromobenzene-treated group. The enzyme activities of epoxide hydrolase and glutathione S-transferase in liver highly increased in Holotrichia pre-medicating group compare with the group treated with only bromobenzene. And we can get the same results in the enzyme activities of superoxide dismutase, catalase and glutathione peroxidase. The level of glutathione followed by Holotrichia pre-medicationg administration, increased as highly as normal group in compare with the group treated with only bromobenzene. Also, the enzyme activities of AL T, AST and $\{gammer}-GTP$ in liver considerably decreased. In conclusion, Holotrichia recovers the damage of liver due to bromobenzene intoxication by the increased activities of lipid peroxidation and bromobenzene scavenging enzymes.

An eight-week-old male ICR mouse, which was induced with acute alcohol and sub-acute alcohol poisoning condition, was administered with bohee tea(Camelia sinensis L) extract. Under the inducement of the sub-acute alcohol poisoning condition, no considerable differences could be found in the blood alcohol concentration of the positive control group and the bohee tea group(p<0.05). The GOT activity of the three groups: bohee tea, Drink, and Alcodex decreased than that of the normal control group(9.064±4.687 unit)(p<0.05). In addition, the blood GOT activity of the dark green tea group dropped by 81.44% compared with that of the positive control group. On the other hand, the blood GTP activity of the bohee tea group decreased by 5.2% as opposed to that of the positive control and the Drink that decreased by 7.5% as opposed to that of the positive control. The hepatic ADH activity of the bohee tea increased by 22.7%, as opposed to that of the positive control group. The Drink, however, had an increase rate of 33.6%. In the case of the hepatic ALDH activity of the liver, no significant differences were ever recorded among all groups, except for the positive control group. Due to an intake of bohee tea extract, the hepatic ALDH activity decreased by 77.27% which could not be seen in the positive control group. However, Drink and A1codex had a decrease could be seen(p<0.05).

Objectives: The purpose of this study is to identify prevalence and related factors of the elderly, who took health examination, with metabolic syndrome. Methods: The health examination and lifestyle survey were performed for 21,512 adults at 60 years of age or older who took health examination in H health promotion center during January-March 2009. Results: The prevalence of metabolic syndrome for the subject was 24.0%. Of the subject with metabolic syndrome, the prevalence of the diseases was obesity 60%, abdominal obesity 78.5%, hypertension 82.6%, dyslipidemia 89.7% and diabetes 51.9%. In comparison of the relationship between metabolic syndrome and other diseases, the male subject with metabolic syndrome were significantly higher in BMI, waist circumference, systolic/diastolic blood pressure, hemoglobin, AST, ALT, $\gamma$-GTP, TG, AC glucose, creatinine than normal male(p<0.001). In comparison of the relationship between metabolic syndrome and lifestyle, more drinking frequency and amount in male and more drinking frequency in female were associated with increased risk of metabolic syndrome(p<0.01). Regardless of exercise intensity, practice of exercise contributed to reduce the risk of metabolic syndrome(p<0.01). Conclusion: In conclusion, TLC program, focused on lifestyle behaviors which is strongly associated with the prevalence of metabolic syndrome, should be developed for the improvement of life quality in the elderly with metabolic syndrome.
